TMC Develops ALS Compressors
TMC Compressors of the Seas is launching a new range compressors designed to work air lubrication systems (ALS) for the shipping and offshore industries to help ships further reduce fuel consumption and emissions to air.The Norway-based supplier of compressed air systems for marine and offshore use said in a press note that the air lubrication system is a method used to reduce the resistance between the ship’s hull and seawater by using air bubbles. The air bubble distribution across the hull surface reduces the resistance working on the ship’s hull, creating energy-saving effects.TMC’s marine compressed air systems for air lubrication systems can be utilised to generate the required stream of air bubbles that passes continuously beneath the ship’s surface…
MT-FAST Fuel-saving Device Installed on 500 Vessels
MT-FAST, a fuel-saving device jointly developed by NYK Group company MTI Co. Ltd. and Tsuneishi Holdings Corporation, has now been installed on over 500 vessels. Operational data has proven the device to be effective in saving fuel.MT-FAST is a multi-blade device that can be attached to a ship’s hull to improve the propeller's propulsion efficiency.A ship moves forward when the engine rotates the propeller, which sucks in the water in front of it and propels that water backwards, creating the force that pushes the vessel forward. However, when converting the rotational power into propulsive power, a swirling flow that reduces propulsion…
Underwater PBCF Installations Bring Fuel Savings
Last month Hydrex installed Propeller Boss Cap Fins (PBCF) on two tankers during their respective stops in Ghent and Antwerp. As a result of the underwater operation, the ships will not have to wait for their next drydock visit to start benefitting from the fuel savings the PBCF’s will bring them. The Propeller Boss Cap Fins (PBCF) is a device for propeller efficiency improvement developed by Mitsui O. S. K. Lines, Ltd. The PBCF can recover energy loss of a propeller hub vortex in the propeller’s backward flow.
Energy-Saving Propeller Boss Cap Fins System
Mitsui O.S.K. Lines, Ltd. (MOL; President: Koichi Muto) and MOL Techno-Trade, Ltd. (MOL Tech; President: Hidehiro Harada) today announced that the energy-saving Propeller Boss Cap Fins (PBCF), developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd., and Mikado Japan, Ltd., and sold by MOL Tech, has now been ordered for 2,000 vessels worldwide. The PBCF is an energy-saving device attached to the propellers of a vessel. It breaks up the hub vortex generated behind the rotating propeller…
